2 Push the ejectors outward on both ends of the memory module socket, to release the memory module from the socket.

Installing memory modules

Steps
1 Locate the appropriate memory module socket.
2 Open the ejectors on the memory module socket outward to allow the memory module to be inserted into the socket.
3 Align the edge connector of the memory module with the alignment key of the memory module socket, and insert the memory module
in the socket.
CAUTION: Do not apply pressure at the center of the memory module; apply pressure at both ends of the memory
module evenly.
NOTE: The memory module socket has an alignment key that enables you to install the memory module in the socket in
only one orientation.
4 Press the memory module with your thumbs until the socket levers firmly click into place.
5 Repeat step 1 through step 4 of this procedure to install the remaining memory modules.
Next steps
1 If applicable, install the air shroud.
2 To verify if the memory module has been installed properly, press F2 and navigate to System Setup Main Menu> System BIOS >
Memory Settings. In the Memory Settings screen, the System Memory Size must reflect the updated capacity of the installed
memory.
3 If the value is incorrect, one or more of the memory modules may not be installed properly. Ensure that the memory module is firmly
seated in the memory module socket.
4 Run the system memory test in system diagnostics.
